Squeak E Beans is one of the five Jack Russell terriers already in Carey's brood. The three new pups will also be joining dogs Cha Cha, Jackie Lambchops, JJ, and Jill E. Beans (who appeared in Carey's "All I Want for Christmas Is You" remix with Justin Bieber in 2011).

The puppies just missed sharing a birthday with Carey and hubby Nick Cannon's twins, who turned two April 30 – the same day their parents celebrated their 5-year wedding anniversary. The couple, who renew their vows each year, dressed as Cinderella and Prince Charming (with the twins in gender-appropriate mini-me outfits) for their re-commitment ceremony at Disneyland last month.
